I know pretty much nothing about electricity, so this is news to me. I've done this before, like others, in order to allow UPSs to support more devices (without overloading them, of course-I only get the kind with load meters on them).
So, a step sine wave created by a UPS could destroy a surge protector, but wouldn't harm equipment plugged directly into the UPS?

If they UPS runs on batteries it will usually generate a step sine wave which may destroy surge protectors (in particular tricky to find power strips without surge protector) http://isc.sans.edu/diary.html?storyid=9319 David Lum // SYSTEMS ENGINEER NORTHWEST EVALUATION ASSOCIATION (Desk) 971.222.1025 // (Cell) 503.267.9764 NOTICE: Florida has a broad public records law.
